SPECIFICATION forming part of Letters Patent No. 735,558, dated August4, 1903.

Application filed November 14, 1902. Serial No. 1311380. (No model.)

To all whom it may concern:

Be it known that I, DANIEL A. MORRISON, residing at Winter Harbor, inthe county of Hancock and State of Maine, have invented certain new anduseful Improvements in VVhiflietrees; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to whiflietrees; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figurel is a plan viewof D is the whiffletree, which ispivoted on a pin e in the middle part of the clevis.

E is a chain or other flexible connection which passes around the sheaveO and has its ends connected to the inner or adjacent draft-tugs of theanimals.

F represents chains or other flexible connections which are connected tothe ends of the whiffletree and to the outer tugs of the draft-animals.

The peculiar formation of the clevis and sheave prevents the chain Efrom ever catching'or becoming jammed in the clevis.

What I claim is The combination, with a clevis having at its front endconverging portions and a forked jaw which is narrower than the mainportion of the clevis, of a draft attachment connected to the rear endof the clevis, a sheave j ournaled in the said forked jaw withits groovearranged to form a continuation of the said converging portions, aWhiffietree pivoted in the middle part of the clevis and free to rockwithout disturbing the alinement of the draft attachment and sheave, aflexible connection passing over the said sheave, andconnections'attached to the ends of the whiffletree, substantially asset forth.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL A. MORRISON.
